RE: What windspeed grounds you?
Same thing in Oklahoma, if you don't fly in wind, you won't fly much. Our field is at the lake. When it is calm in town, going out to the field usually finds a breeze coming off the water. I tried my Sig Kadet Sr in about 20 - 25 MPH wind once and had to shoot the landing 5 times before I got it on the ground safely. A Sr. flyer (the best pilot in our club) was there with me coaching me through it, without him, I probably would have trashed the plane. Now I'm flying fully symmetrical wing stick, so it takes the wind quite a bit better. Flew in 20 MPH wind last Sunday no problems...
